Excessive wear? Need input.
 
hi guys I just want to get an advice on this. I just had a vvt engine rebuilt top and bottom and started up. The rings has not been broken in yet so the majority of it has been from idle. I just drained the oil and it seems like the magnetic drain plug has picked up quite a bit of metal. What do you guys think? The car has done about 45 minutes of idling. At one point the engine was idling at around 1500-2000 rpm.https://cimg4.ibsrv.net/gimg/www.mia...c97cf89502.jpg

Probably fine. The real question is why did you let it idle for 45 minutes? I start, check a few basics, the drive. 25 miles later, I race.

its my understanding that a brand new engine/rebuilt engine will have metal debris during break in period. and is why an early oil change is recommended after a few hundred miles to dump all that metal out.

I just rebuilt my engine, so we will see in a few weeks how my oil looks like.

I had trouble getting the car to idle. So I spent some time learning to get my idle on megasquirt.

Thanks for the input guys. Car is getting the rings seated asap!

So im not stuhpid for setting the boost to allofitafter 2 days?

I personally think you should get into the boost and the vacuum as soon as the car is running, so the rings seat properly. I generally try to avoid high RPM though.

I wouldn't be thrilled to find metal bits in the oil pan after a rebuild, but it's par for the course.
